As long as you are comfortable building from source, it shouldn't
be too hard to get things working; dropping in executable from
different major releases is not likely to work.
You probably should read this page, though:
http://www.postgresql.org/support/versioning/
The bug fix level of the 8.4 release that you are using is missing
almost four years of fixes for bugs and security vulnerabilities.
The 8.3 version has hit end of life; it is no longer supported. It
also is missing about four years of fixes which had been made
available before it hit EOL. Bug fix (minor) releases can be
applied without any conversion effort, and with very low risk of
any compatibility problems.
